Key Takeaways
- • YMTC-backed Changcun Industry Investment Fund has taken a strategic stake in SOI Micro, a Guangzhou-based semiconductor manufacturer focused on alternative chipmaking technology, signaling China's continued push to reduce dependence on overseas semiconductor processes.
- • SOI Micro is developing fully depleted silicon-on-insulator (FD-SOI) technology targeting 28-nanometre-class logic processes, positioning this approach as a complementary route to mainstream chipmaking rather than direct competition with advanced nodes.
- • The company is led by Ye Tianchun, a veteran semiconductor technologist who previously headed the Chinese Academy of Sciences' Institute of Microelectronics and served as chief technologist for China's state-backed "02" project on domestic chip equipment and fabrication.
- • Changcun Industry Investment Fund, established in 2023 by YMTC alongside Hubei's state-backed integrated circuit investment vehicle, is expanding beyond its traditional memory-chip supply-chain focus into specialized logic manufacturing.
- • Investment size and stake percentage were not disclosed; SOI Micro did not respond to requests for comment on the transaction details.
Summary
A venture capital fund controlled by Yangtze Memory Technologies Corp (YMTC), China's leading NAND flash memory producer, has invested in SOI Micro, a domestic semiconductor manufacturer developing alternative chipmaking pathways. The investment underscores China's strategic effort to build a self-reliant semiconductor ecosystem insulated from international technology restrictions and supply-chain vulnerabilities.
SOI Micro, founded in Guangzhou in 2022, specializes in fully depleted silicon-on-insulator (FD-SOI) technology—a low-power chipmaking process designed to serve as a complementary manufacturing route rather than compete directly with cutting-edge advanced nodes. The company is targeting 28-nanometre-class logic processes, a segment where FD-SOI technology offers distinct power efficiency advantages for specific applications. This positioning reflects a broader Chinese strategy of developing multiple pathways within semiconductor manufacturing rather than pursuing single-node dominance.
The investment vehicle, Changcun Industry Investment Fund, was established in 2023 by YMTC in partnership with the Hubei Integrated Circuit Industry Investment Fund, a state-backed investment entity based in Wuhan. While Changcun has historically concentrated on memory-chip supply-chain players, this SOI Micro investment marks a notable expansion into specialized logic manufacturing—a departure from its core mandate that signals YMTC's confidence in alternative process technologies as part of a diversified domestic chip strategy.
SOI Micro is led by Ye Tianchun, a prominent figure in China's semiconductor sector who previously directed the Chinese Academy of Sciences' Institute of Microelectronics and served as chief technologist for the "02" project, a major state initiative aimed at advancing domestic chipmaking equipment and fabrication capabilities. His leadership brings significant government connections and technical credibility to the venture. The specific investment amount and equity stake were not disclosed, and SOI Micro declined to comment further on the transaction.
